HL7-defined code system of concept that specify the scheme used when any alternative character sets are specified in the second or later iterations of MSH-18 Character Set, and if any special handling scheme is needed. Used in HL7 Version 2.x messaging in the MSH segment.

2.3 The character set switching mode specified in HL7 2.5 The character set switching mode specified in HL7 2.5, section 2.7.2 and section 2.A.46, "XPN - extended person name". 2.3.1 Note that the escape sequences used in this mode do not use the ASCII “esc” character, as defined in ISO 2022-1994. They are “HL7 escape sequences” as first defined in HL7 2.3, sec. 2.9.2. (Also, note that sections 2.8.28.6.1and 2.9.2 in HL7 2.3 correspond to sections 2.16.93 and 2.7.2 in HL7 2. 5.) 2015-07-13
